iiIN CASE OF EMERGENCYIf your vessel requires assistance, contact other vessels andthe Coast Guard by sending a Distress call on Channel 16.Or, transmit your Distress call using digital selective callingon Channel 70.INSTALLATION NOTEThe installation of this equipment should be made in such amanner as to respect the EC recommended electromagneticfield exposure limits (1999/519/EC).The maximum RF power available from this device is 25watts. The antenna should be installed as high as possiblefor maximum efficiency and that this installation height shouldbe at least 5 meters above ground (or accessible) level. In thecase where an antenna cannot be installed at a reasonableheight, then the transmitter should neither be continuouslyoperated for long periods if any person is within 5 meters ofthe antenna, nor operated at all if any person is touching theantenna.In all cases any possible risk depends on the transmitterbeing activated for long periods. (actual recommendation lim-its are specified as an average of 6 minutes) Normally thetransmitter is not active for long periods of time. Some radio li-censes will require that a timer circuit automatically cuts thetransmitter after 1–2 minutes etc.Similarly some types of transmitter, SSB, CW, AM, etc. have alower ‘average’ output power and the perceived risk is evenlower.USING DIGITAL SELECTIVE CALLING (Ch 70)DISTRESS CALL PROCEDURE1.
